1 Claim. (Cl. 4-11) This invention relates to a mobile toilet and haspar ticular reference wherein is disposed a plurality of toiletfacilities and with the housing being supported by ground wheels thatpermit the device to be transported from place to place providing atemporary toilet facility for use in construction projects or the like.

It has been common practice heretofore on construction projects to builda temporary toilet that is usually placed over an opening formed in theground, which use has resulted in frequently contaminating wells andgenerally creating an unsanitary condition, and it is the purpose ofthis device to avoid such unsanitary conditions, and to provide aconstruction that is readily connectible to a water supply line forproviding conventional flush toilets and urinals, and with the flushtoilets being connected to a flexible soil pipe that is detachablyconnected to the conventional sewer lines or to the Well known septictanks.

A further and important object of this invention resides in a toiletassembly of the flush type that is connected with a soil line and withthe soil line being connected with a water supply line whereby the soilline may be conveniently and easily flushed out when the device is to betransported to another site.

A further object of the invention resides in novel closure doors for apair of toilet facilities that serve jointly as a closure door and as anadequate shield to afford privacy for an individual or individualsemploying the toilets.

Novel features of construction and arrangement of parts will be moreclearly apparent during the course of the following description,reference being had to the accompanying drawings wherein has beenillustrated a preferred form of the device and wherein like charactersof reference are employed to denote like parts throughout the severalfigures.

Referring to the drawings:

Figure 1 is a side elevation of a device constructed in accordance withthe invention,

Figure 2 is a vertical transverse section taken substantially on line2-2 of Figure 1,

Figure 3 is a fragmentary enlarged section illustrating the means forflushing the soil line,

Figure 4 is a horizontal section taken substantially on line 44 ofFigure 1 and,

Figure 5 is a longitudinal vertical section taken substantially on line5--5 of Figure 4.

Referring specifically to the drawings, the numeral 5 designates apreferably rectangular shape channel iron frame that constitutes thebase member for the device. The frame 5 is supported by a pair of groundwheels 6 through the medium of the usual axle 7 and spring mountings 8.The draft device 9 having a hitch 10 is employed in a conventionalmanner for towing the device from place to place.

Rigidly fixed upon the upper side of the frame 5 is a floor panel 11,here shown as being substantially co-extensive with the frame 5. Fixedwith respect to the floor 11 are end walls 12 and side walls 13 and 14.A trans- 2,772,420 Patented Dec. 4, 1956 'ice verse partition 15 spansthe device and is connected to the walls 13 and 14 in any desirablemanner and with the several walls and partition being of equal heightadequate to permit an individual to stand erect therein. The wall 14 isformed shorter in length than the wall 13, providing a pair of dooropenings 16 that provide access to separate toilet areas A and B. Alongitudinally extending partition 17 divides each toilet area A and Binto cubicles 18 and 19. A roof panel 20 overlies the upper end of thetoilet areas and extends slightly beyond the walls 12, 13 and 14. Theroof 20 is bowed transversely, as clearly illustrated in Figure 2, andis slightly elevated to provide ventilating air openings 21 throughoutthe periphery of the device. The several wall panels, partitions and theroof panel are preferably formed of sheet metal. The floor panel 11 islikewise preferably formed of sheet metal and its surface may beroughened or corrugated to prevent slipping of an individual.

Closure doors 22 are hinged as at 23 to the corners of the device andserve to completely overlie and close the door openings 16. Each of thedoors 22 are formed of sheet metal embodying a relatively wide panel 24and an integral angularly disposed portion 25. The upper and lower endsof the doors are provided with a connecting web portion 26 serving torigidly support the panel 24 and its adjacent angle portion 25, againstflexing. As clearly shown in Figure 4, the doors 22 are of such widththat when disposed in a predetermined open position will effectivelyblock the view of anyone passing the device, thus the doors 22 serve thedual purpose as a closure device and as a shield for a person employingthe toilet. Each of the doors are provided with a conventional hasp 27through the medium of which the doors may be locked at such times as thedevice is not in use or when being transported. Adjustable ground props28 are carried at each corner of the device and serve to rigidly bracethe device, in use.

Disposed within each cubicle 18 is a flush toilet 29 of conventionalconstruction. Disposed within the cubicles 19 are urinal troughs 30.Each of the toilets 29 have communication with a common soil pipe 31rigidly supported upon the lower side of the frame, and with the soilpipe 31 extending longitudinally of the frame to extend slightly beyondone end of the device as clearly illustrated in Figure 5. The soil pipe31 is provided with upwardly directed laterals 32 that have connectionwith the commode s 3 3 embodied in the toilets 29. It is desiralble in adevice of this type that the soil pipe 31 be formed of steel as a meansof reducing the overall weight of the unit. The extended end of the soilpipe 31, as in Figure 5, is preferably threaded at 34 for detachablethreaded connection with a threaded ring 35 carried at one end of aflexible soil pipe 36. The soil pipe 36 at its opposite end hasdetachable connection with a sewer or septic tank connection 37 in anydesirable manner. The soil pipe 36 during the transportation of thedevice is preferably stored beneath the frame 5 in any suitable manner.The opposite end of the soil pipe 31 is provided with a reducingcoupling 33 that has threaded connection with a water supply line 39that terminates in a conventional cut-off hose bib 40, through themedium of which a hose or other water supply line may be readilyconnected to the line 39 to serve as a means for quiclcly andconveniently cleansing the soil pipes 31 and 36 when the device is to betransported to a new location. The urinals 30 are each connected withthe soil pipe 31 by drain pipe 41 in a convenient manner. A water supplypipe 42, disposed at one side of the device is provided with a hose bib43 for connection with a hose or other water supply connection. The pipe42 serves as a water supply means to the flush toilets 29 and theurinals 30.

In the use of the device, when it has been transported to apredetermined location, it is positioned adjacent either a septic tankor a sewer line. The several props 23 are then lowered and anchored insupper-ting position to prevent shifting of the unit. The flexible soilpipe 36 is then connected with the soil pipe 31 and with the sewer orseptic tank connection 37. A hose leading from any convenient watersupply is connected with the hose bib 43. The doors 22 are then shiftedto the open angular position as illustrated in Figure 4 providing anadequate clearance to permit the entry to the toilet areas A and B. Anydesiralble means may be employed to fixedly position .the doors in thedesired angularity Where the panel portion 25 serves to eflectivelyblock the view to the interior of the device. Toilets 29 and the urinals3t) serve in their customary manner for workmen or other employees upona construction project. Now, when the device is to be transported to anew location, the hose leading to the hose bib 43 is disconnected andeach of the toilets 29 are flushed to relieve them of any water standingwithin the flush tanks. The operator then connects a water supply hoseto the hose bib 40, and upon opening the valve of the hose bib, water iscontinuously flushed through the soil pipes 31 and 36, efiectivelycleansing them of any accumulated sediment that would ordinarily createan unsanitary and undesirable condition. This flushing is continued overa predetermined period of time calculated to thoroughly remove anydeposits within the soil pipes. The soil pipe 36 is then removed andstored beneath the frame 5 in any suitable brackets provided therefor.The props 28 are then elevated and the hitch coupled with any convenientdraft device for conveying the unit to a new location. The doors 22 arepreferably closed in latch position before the device is transported.

it will be apparent from the foregoing that a very novel and desirabletoilet facility has been provided to effectively serve in that capacityfor construction projects or as a convenient temporary toilet facility.The device provides a sanitary arrangement required under the codes ofcertain municipalities and effectively avoids the common unsanitaryconditions now prevailing in temporary toilets disposed over an openingin the ground. The device is strong, durable, cheap to manufacture, iseasily transported from place to place and is most effective for thepurposes hereinbefore described.

it is to be understood that the invention is not limited to the precisedetails of construction but that changes are contemplated as readilyfall Within the spirit of the invent-ion as determined by the scope ofthe subjoined claim.
